Springsource Acquires RabbitMQ Cloud Messaging Technology

Widely Used Enterprise Messaging Technology Ideally Suited for new Generation of Cloud Applications

PALO ALTO, Calif.—April 13, 2010—SpringSource, a division of VMware, Inc. (NYSE: VMW) and the leader in Java application infrastructure and management, today announced the  acquisition by VMware of Rabbit Technologies, Ltd., an open source software company based in the United Kingdom. SpringSource will add the RabbitMQ open messaging system into its suite of technologies that reduce the complexity associated with development, deployment and management of enterprise applications. Terms of the deal were not disclosed.

As organizations increasingly build and deploy applications in a cloud environment, the infrastructure to support this new model is evolving.  A new type of lightweight, reliable, scalable and portable messaging system is required to support the routing of user requests to the appropriate resources regardless of where they may reside. RabbitMQ is a leader in this field and with this acquisition, SpringSource will employ the principal contributors to RabbitMQ, the open source standards-based messaging system that enables applications or components of applications to more effectively communicate with each other.

“While messaging has always been a key infrastructure element used in the creation of enterprise applications, cloud applications require a fundamentally different messaging infrastructure,” said Rod Johnson, general manager of the SpringSource division of VMware. “By adding RabbitMQ to our suite, SpringSource can extend its emerging application platform with another element of technology that is critical to modern virtual and cloud deployment models.”

Providing clear integration with the Spring Framework will also allow a significant community of Spring developers to leverage RabbitMQ as they evolve their applications from traditional datacenters into private and public cloud deployments. RabbitMQ will continue to be open source software.  At the same time, SpringSource plans to continue full support for the RabbitMQ developer community. 

“RabbitMQ is an extremely successful technology and forms the backbone for many varied cloud messaging systems,” said Alexis Richardson, chief executive officer and co-founder, Rabbit Technologies, Ltd. “By providing a multi-protocol, completely open, portable messaging system, our technology can be a key enabler of tomorrow’s applications. By joining with enterprise leaders, SpringSource and VMware, RabbitMQ expects to continue to be at the forefront of the movement toward cloud computing. Users and customers will benefit from an organization offering deep and immediate experience with the challenges of managing highly available and stable operations.”
